In addition, when selecting suppliers, the Company upholds the spirit of protecting intellectual property rights by requiring suppliers to provide warranties of non-infringement, as well as licenses and authorizations for the use of relevant technologies, so as to avoid any impact on the Company's rights and interests arising from competition over patents in the marketplace. The Company will continue to track the subsequent developments of the case, prudently assess the potential impact of this matter on its production and operations, and maintain communication with relevant parties. The Company will continue to follow up on and handle this Section 337 Investigation, firmly safeguard the legitimate rights and interests of the Company and all of its shareholders, and fulfill its information disclosure obligations in a timely manner in accordance with applicable regulations.
